Features

Inline overlay — Opens below the cursor, not as a fullscreen app. Dismiss without trace. Pure ANSI escape codes, no libraries. Fuzzy search + typo tolerance — Damerau-Levenshtein distance catches typos. Accent normalization (próximo matches proximo). Recency ranking — Score = fuzzy match + usage count + exponential decay (48h half-life). Pinned commands stay at top. Workflows — Multi-step commands with interactive runner. Each step is a title + command pair. Enter steps forward, Ctrl+X runs all. Zero dependencies — Pure Go standard library. No ncurses, no fzf, no daemon. Single 6.2 MB binary. MCP server — Model Context Protocol over stdin/stdout. Lets AI agents search, add, edit, and execute from your vault.

Install npm install -g decoreba Downloads a prebuilt binary for your platform. No Go toolchain needed. go install github.com/matheuzgomes/decoreba/cmd/decoreba@latest Quick start decoreba # auto-detect context from cwd decoreba git # search within "git" context decoreba add # add a command decoreba edit 0c9 # edit by id prefix decoreba stats # vault statistics See the full reference below.

Usage Palette The overlay appears below your prompt, not fullscreen. Type to fuzzy-search. Enter copies the command. Ctrl+X executes it. NoteShift+Enter also executes, but only in terminals that implement the kitty keyboard protocol (kitty, WezTerm, Ghostty). In most terminals Shift+Enter sends the same byte as Enter and will copy instead.

When results exceed the viewport, an overflow indicator appears (… 3 more). If the terminal is 3 rows or shorter, a graceful message is shown instead. NO_COLOR or --no-color disables all ANSI codes.

Keybindings Universal (every terminal emulator)

Key Action

↑ / Ctrl+K Navigate up

↓ / Ctrl+J Navigate down

Enter Copy selected

1 – 9 Direct select (empty search)

Ctrl+X Execute selected (press twice, or y to confirm)

Ctrl+E Edit selected

Ctrl+S Toggle pin

Backspace (empty) Remove context chip

Tab / Shift+Tab Next / previous field (form)

Esc / Ctrl+C Cancel

Kitty protocol only (kitty, WezTerm, Ghostty)

Key Action

Shift+Enter Execute selected

Execute mode Ctrl+X triggers execution. A confirmation prompt appears: Run this command? y/yes n/no. Press Ctrl+X again or y to confirm. Any other key cancels. With --shell-output, the command text is printed to stdout instead of the clipboard. The shell widget (below) strips the prefix automatically: decoreba docker ps --shell-output # prints "✓ docker ps" or "EXEC:docker ps" Add / Edit form

Five fields: context, title, command, tags, notes. Context autocompletes from existing entries. Tags render as colored chips. Ctrl+W turns the command into a multi-step workflow editor. decoreba edit <id> or Ctrl+E from the palette reopens the form pre-filled. Workflows Commands can have multiple steps. Each step is a title + command pair.

Enter runs the next step. Ctrl+X runs all remaining (confirms first). Esc aborts. Failed steps show ✗. Subprocess I/O routes through /dev/tty so interactive programs still work when piped. Variables Use {{placeholder}} or {{name:default}} in any command. On copy or execute, decoreba prompts for each value inline: $ decoreba deploy

Container name: [web]

Shell integration Completions Generate tab completions for subcommands, contexts, and sync actions: eval "$(decoreba completion bash)" # or zsh / fish Ctrl+O widget Opens the palette pre-filled with whatever you typed. Enter inserts the command at the cursor. Ctrl+X executes (confirms first).

source <(decoreba shell bash) # or zsh Init Installs both widget and completions into your shell rc file in one step. Creates a backup before modifying. decoreba init # interactive decoreba init --yes # non-interactive

Gist sync Sync your vault across machines via a private GitHub Gist. decoreba sync init # create a new Gist and upload decoreba sync push # upload local changes decoreba sync pull # download remote changes decoreba sync status # show ahead/behind/diverged/clean Requires DECOREBA_GIST_TOKEN (classic PAT with gist scope). Pass --encrypt to encrypt with AES-256-GCM before upload. The key is derived from the token.

MCP server Runs a Model Context Protocol server over stdin/stdout. Lets AI agents (Claude Desktop, Cline, etc.) interact with your command vault directly. decoreba mcp

Tool Action

decoreba_search Fuzzy search across all contexts

decoreba_get Look up a command by ID

decoreba_list_contexts List all contexts with counts

decoreba_add Add a new command

decoreba_edit Update an existing command

decoreba_remove Delete by ID

decoreba_execute Run a command and return output

decoreba_stats Vault statistics

Write and delete tools require confirm: true. Dangerous commands (rm -rf /, > /dev/sda, etc.) are blocked by a built-in denylist. Auto-backup runs before every modification.

Data Single JSON file. Atomic writes (save to .tmp, rename over target).

Design

Appear, don't replace. Inline overlay, not alternate screen. The terminal is exactly as it was before. Right answer before you finish typing. Fuzzy + typo tolerance + recency + pinning. Keyboard-first. Every action has a shortcut. The hint line teaches them progressively. No mouse. Context over categories. Commands live under the tool they belong to. Auto-detection from cwd. Accessible. NO_COLOR and --no-color disable all ANSI escape codes.
